1Back-office consolidation post-rebrandCost & operationsIdentified$4.4M–$14M

The rebranding as Marsh brief flags this opportunity: Back-office consolidation post-rebrand. Lead with a fixed-scope 4-week entry offer that proves value quickly, then grow it into the cost program office and the delivery of the largest levers.

From opportunity: Back-office consolidation post-rebrand

Why now: Unifying under one "Marsh" brand from 2026, with a new tech unit; Guy Carpenter becomes Marsh Re.
Buyers: CFO Mark McGivney · COO · CEO John Doyle · Head of Transformation
Our sponsor: Accenture Strategy & Consulting MD for Financial Services, with the account's client lead
Entry: A 4-week cost baseline and value-at-stake review: spend cube, benchmarks and 3-5 levers with savings ranges, ready for the next earnings or board cycle.. No CAL account team today. Enter through the sponsor's network and a short point-of-view note to CFO Mark McGivney.
Proof points: Cost and operating model transformation case studies

Deal size$4.4M–$14M

Pursuit cost$110K

Win probability15%

Estimate: Estimate. Pursuit cost is about 22 person-weeks of account, sponsor and SME time at a blended $5,000 per person-week, including extra effort to win a first meeting without an account team. The entry offer itself is a fixed fee of roughly $100k, or an Accenture investment if the pursuit is contested. The deal range is the 12-24 month follow-on (the cost program office and the delivery of the largest levers), scaled for a large client from a reference range of $8-25M. It is not based on client budget data. Win probability of 15% is a planning assumption for an account without a CAL tier.
